Abstract
A control device and a method for estimating a driving range for a vehicle. The method comprises, based on available driving energy for the vehicle, estimating distance to empty taking into account an estimated variation in rolling resistance of the vehicle, wherein said estimated variation in rolling resistance of the vehicle is determined using a predetermined transient rolling resistance model into which transient tire temperature effects on rolling resistance are incorporated.
Claims23
A method, performed by a control device, for estimating a driving range for a vehicle, the method comprising:
- based on available driving energy for the vehicle, estimating the driving range taking into account an estimated variation in rolling resistance of the vehicle, wherein the estimated variation in rolling resistance of the vehicle is determined using a predetermined transient rolling resistance model into which transient tire rubber temperature effects on rolling resistance are incorporated, wherein the transient tire rubber temperature used in the model is a tire rubber temperature of at least a portion of the tire that face towards a road surface;
- and
- approving or adjusting the planned upcoming driving event in dependence of whether the estimated driving range is determined to be sufficient or not for completing the planned upcoming driving event.
A method, performed by a control device, the method comprising:
- estimating a driving range for a vehicle for a planned upcoming driving event, said estimating comprising:
- based on available driving energy for the vehicle, estimating the driving range taking into account an estimated variation in rolling resistance of the vehicle,
- wherein the estimated variation in rolling resistance of the vehicle is determined using a predetermined transient rolling resistance model into which transient tire rubber temperature effects on rolling resistance are incorporated, wherein the transient tire rubber temperature used in the model is a tire rubber temperature of at least a portion of the tire that face towards a road surface;
- and
- approving or adjusting the planned upcoming driving event in dependence of whether the estimated driving range is determined to be sufficient or not for completing the planned upcoming driving event.
A computer program product stored on a non-transitory computer-readable medium, said computer program product for estimating a driving range for a vehicle, wherein said computer program product comprising computer instructions to cause one or more computing devices to perform the following operations:
- based on available driving energy for the vehicle, estimating the driving range taking into account an estimated variation in rolling resistance of the vehicle, wherein the estimated variation in rolling resistance of the vehicle is determined using a predetermined transient rolling resistance model into which transient tire rubber temperature effects on rolling resistance are incorporated, wherein the transient tire rubber temperature used in the model is a tire rubber temperature of at least a portion of the tire that face towards a road surface;
- and
- approving or adjusting the planned upcoming driving event in dependence of whether the estimated driving range is determined to be sufficient or not for completing the planned upcoming driving event.
A control device configured to estimate a driving range for a vehicle, wherein the control device is configured to:
- based on available driving energy for the vehicle, estimate the driving range taking into account an estimated variation in rolling resistance of the vehicle, wherein the estimated variation in rolling resistance of the vehicle is determined using a predetermined transient rolling resistance model into which transient tire temperature effects on rolling resistance are incorporated, wherein the transient tire rubber temperature used in the model is a tire rubber temperature of at least a portion of the tire that face towards a road surface;
- and
- approving or adjusting the planned upcoming driving event in dependence of whether the estimated driving range is determined to be sufficient or not for completing the planned upcoming driving event.
A vehicle comprising a control device configured to estimate a driving range for a vehicle, wherein the control device is configured to:
- based on available driving energy for the vehicle, estimate the driving range taking into account an estimated variation in rolling resistance of the vehicle, wherein the estimated variation in rolling resistance of the vehicle is determined using a predetermined transient rolling resistance model into which transient tire temperature effects on rolling resistance are incorporated, wherein the transient tire rubber temperature used in the model is a tire rubber temperature of at least a portion of the tire that face towards a road surface;
- and
- approving or adjusting the planned upcoming driving event in dependence of whether the estimated driving range is determined to be sufficient or not for completing the planned upcoming driving event.
